Abstract

This novel sprayer distribution system complements a packed column. Its tubes (2, 4) and nozzles (3), distribute the fluid. All nozzle outlets occupy the same level. In this new development, all nozzles are equal sections of glass tubing. Each outlet has a cut edge, made by e.g. a diamond cutter, and otherwise untreated. It is alternatively an untreated edge, which is cut by a clean break. Also claimed are: a column employing the distributor; use of the column for gas/liquid mass exchange, in which the liquid corrodes metals but not the packing; and use for gas/liquid or liquid/liquid sorption.

Description

Die Erfindung betrifft eine Verteilvorrichtung für eine Kolonne gemäss Oberbegriff von Anspruch 1; ferner eine Kolonne mit einer erfindungsgemässen Verteilvorrichtung und Verwendungen der Kolonne beziehungsweise der Verteilvorrichtung.The invention relates to a distribution device for a Column according to the preamble of claim 1; furthermore a Column with a distribution device according to the invention and uses of the column or Distribution device.

Es ist hinsichtlich Form und Werkstoff eine Vielzahl von Verteilvorrichtungen bekannt, mit denen Flüssigkeiten gleichmässig auf Packungen von Kolonnen aufgebracht werden können. Für die Verteilung korrosiver Flüssigkeiten sind im Handel gläserne Zulaufeinsätze für eine punktförmige Flüssigkeitsaufgabe oder Ringbrausen bekannt. Die Ringbrause besteht aus einem ringförmigen Glasrohr, das ein Grundloch-Ausflusssystem aufweist. Zwischen den einzelnen Grundlöchern des Ausflusssystems bestehen in der Regel Unterschiede bezüglich der Geometrie ihrer Austrittsöffnungen, aufgrund derer sich unterschiedliche Ausflussraten ergeben und somit eine gleichmässige Verteilung praktisch nicht durchführbar ist. Zudem eignen sich Ringbrausen nur für Kolonnen mit relativ kleinen Durchmessern und es ist keine über den gesamten Querschnitt gleichmässige Verteilung der Austrittsöffnungen möglich.It is a variety of in terms of shape and material Known distribution devices with which liquids evenly applied to packed columns can be. For the more corrosive distribution Liquids are commercially available feed inserts for a punctiform liquid feed or ring showers known. The ring shower consists of an annular one Glass tube that has a blind hole drainage system. Between the individual holes in the outflow system there are usually differences in the Geometry of their outlet openings, on the basis of which result in different outflow rates and thus one even distribution practically not feasible is. In addition, ring showers are only suitable for columns relatively small diameters and there is none over that uniform distribution of the entire cross section Outlet openings possible.

Es ist Aufgabe der Erfindung, eine inerte Verteilvorrichtung zu schaffen, die sich für auf Metalle korrosiv wirkende Flüssigkeiten eignet und die gleiche Ausflussraten aller Verteildüsen oder eines Teils der Düsen ermöglicht. Ferner soll es möglich sein, für Kolonnen mit beliebig grossen Durchmessern Verteilvorrichtungen konstruieren zu können. Die durch Anspruch 1 definierte Vorrichtung löst diese Aufgaben.It is an object of the invention to provide an inert To create distribution device that is suitable for on metals corrosive liquids and the same Flow rates of all or some of the distribution nozzles Allows nozzles.

Die Austrittsöffnungen der Düsen sind vorzugsweise alle auf gleichem Niveau angeordnet. Zumindest zu einem Teil sind die Düsen aus gleichen Glasrohrstücken gefertigt. Jede Austrittsöffnung weist einen Rand auf, der durch eine mittels Fräseschnitt gebildete und sonst unbehandelte Kante oder eine unbehandelte Glasbruchkante gebildet ist. Zur Bildung des Fräseschnitts kann ein bei der Glasbearbeitung gebräuchliches, Diamantkörner tragendes Fräseblatt verwendet werden.The distribution device according to the invention for a column includes a system of manifolds and nozzles for one Fluid. The outlet openings of the nozzles are preferred all arranged at the same level. At least to one Part of it are the nozzles made of the same glass tube pieces manufactured. Each outlet opening has an edge, which is formed by a milling cut and otherwise untreated edge or an untreated broken glass edge is formed. A can be used to form the milling cut of glass processing, diamond grains load-bearing cutter blade can be used.

Soll jede Düse in gleichem Masse zur Verteilung der Flüssigkeit beitragen, so müssen alle Düsen aus gleichen Glasrohrstücken gefertigt und die Austrittsöffnungen auf gleichem Niveau angeordnet sein. In besonderen Fällen kann es aber vorteilhaft sein, für einzelne Düsen, beispielsweise für randständige, andere Ausflussraten vorzusehen. Dies kann durch andere Düsendurchmesser und/oder Anordnung der Austrittsöffnungen auf anderem Niveau erreicht werden.Should each nozzle be used to distribute the Liquid contribute, so all nozzles must be the same Glass tube pieces made and the outlet openings be arranged at the same level.
